  • Product overview

    Abcam’s Human IL-1 beta ab46052 in vitro ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of IL-1 beta in Human serum, plasma, buffered solutions or cell culture medium.

    A monoclonal antibody specific for IL-1 beta has been coated onto the wells of the microtiter strips provided. Samples, including standards of known IL-1 beta concentrations, control specimens or unknowns are pipetted into these wells. During the first incubation, the standards or samples and a biotinylated monoclonal antibody specific for IL-1 beta are simultaneously incubated. After washing, the enzyme Streptavidin-HRP, that binds the biotinylated antibody is added, incubated and washed. A TMB substrate solution is added which acts on the bound enzyme to induce a colored reaction product. The intensity of this colored product is directly proportional to the concentration of IL-1 beta present in the samples.

    This kit will recognize both endogenous and recombinant Human IL-1 beta.

  • Research areas
  • Function
    Potent proinflammatory cytokine. Initially discovered as the major endogenous pyrogen, induces prostaglandin synthesis, neutrophil influx and activation, T-cell activation and cytokine production, B-cell activation and antibody production, and fibroblast proliferation and collagen production. Promotes Th17 differentiation of T-cells.
  • Tissue specificity
    Expressed in activated monocytes/macrophages (at protein level).
  • Sequence similarities
    Belongs to the IL-1 family.
  • Post-translational
    modifications
    Activation of the IL1B precursor involves a CASP1-catalyzed proteolytic cleavage. Processing and secretion are temporarily associated.
  • Cellular localization
    Cytoplasm, cytosol. Lysosome. Secreted, exosome. Cytoplasmic vesicle, autophagosome. Secreted. The precursor is cytosolic. In response to inflammasome-activating signals, such as ATP for NLRP3 inflammasome or bacterial flagellin for NLRC4 inflammasome, cleaved and secreted. IL1B lacks any known signal sequence and the pathway(s) of its secretion is(are) not yet fully understood (PubMed:24201029). On the basis of experimental results, several unconventional secretion mechanisms have been proposed. 1. Secretion via secretory lysosomes: a fraction of CASP1 and IL1B precursor may be incorporated, by a yet undefined mechanism, into secretory lysosomes that undergo Ca(2+)-dependent exocytosis with release of mature IL1B (PubMed:15192144). 2. Secretory autophagy: IL1B-containing autophagosomes may fuse with endosomes or multivesicular bodies (MVBs) and then merge with the plasma membrane releasing soluble IL1B or IL1B-containing exosomes (PubMed:24201029). However, autophagy impacts IL1B production at several levels and its role in secretion is still controversial. 3. Secretion via exosomes: ATP-activation of P2RX7 leads to the formation of MVBs containing exosomes with entrapped IL1B, CASP1 and other inflammasome components. These MVBs undergo exocytosis with the release of exosomes. The release of soluble IL1B occurs after the lysis of exosome membranes (By similarity). 4. Secretion by microvesicle shedding: activation of the ATP receptor P2RX7 may induce an immediate shedding of membrane-derived microvesicles containing IL1B and possibly inflammasome components. The cytokine is then released in the extracellular compartment after microvesicle lysis (PubMed:11728343). 5. Release by translocation through permeabilized plasma membrane. This may occur in cells undergoing pyroptosis due to sustained activation of the inflammasome (By similarity). These mechanisms may not be not mutually exclusive.

Answer

Thank you for your reply.

If you diluted the controls in the recommended volume of diluent, then you should have ended up with the concentration that is indicated on the control vials. Was there no concentration listed on the vials? If there is no concentration listed on the vials, please provide me with the lot numbers you have for each of these kits and will be happy to find out the concentration for you.

I am not sure if these controls are actually supposed to give you a concentration at the max end of the scale, I would suspect that they are designed to give a reading in the mid range. Based on the numbers you provided and the range that each kit detects, that appears to be the case.

If there is anything else I can help you with, please let me know.

Answer

Thank you for contacting Abcam.

For all three of those ELISA kits, there are standards and controls (4 vials of control per kit)provided and you should reconstitute those samples in the correct diluent depending on your sample types.

Please let me know if there is anything else I can help you with or if this does not answer your question.

Answer

Gracias por contactarnos.


He querido comprobar la posibilidad de presentar reactividad cruzada entre ratón y humano en los kits contra las citoquinas que mencionas.

Tenemos varios kits contra dichas citoquinas específicos para ratón, y específicos para humano. Después de estudiar la homología entre secuencias, me temo que no podemos predecir que exista reactividad cruzada entre especies. Experimentalmente tampoco tenemos datos para confirmarlo.

Siento no poder ser de mas ayuda. No dudes en contactarnos para cualquier otra consulta.
